XR-T5650
XR-T5650 is PCM Line Receiver & Clock Recovery Circuit manufactured by Exar.
DESCRIPTION
FUNCTIONAL BLOCK DIAGRAM
The XR-T5650 is a monolithic bipolar IC designed for PCM type line receiver applications operating at T1. T148C, T1C and 2 M bitls data rates. It provides all the active circuitry required to perform automatic line build out (ALBO)' threshold detection, positive and negative data and clock recovery.
Clock recover using a crystal filter instead of an LC tank circuit is also available as XR-T5750.
